3 Claims.

This invention relates to magazines or retainers for use in machines for installing belt-hooks type, and more especially to a secured in hinged relationship thereto by a suitable rod or pin member.

It is an object of the present invention to provide a retainer or magazine for the above purpose, in which the belt-hooks when inserted shall be maintained in positive alignment prior to, and during, the clamping action of the lacer.

It is a further object to provide such a magazine, in which the hooks shall be retained in place by a clamping action exerted uniformly from end to end of the group of hooks to be installed.

It is a further object to provide a magazine as hereinbefore described in which the clamping force shall be applied symmetrically of the hook assembly, thereby eliminating any tendency of the hooks to be tilted to one side.

It is a further object to provide a magazine as hereinbefore described in which the clamping eifort is exerted as a simple compressive force,

they may bear.

It is a further object to provide a belt-hook magazine which shall be simple in design, adaptable to a variety of sizes of belt-hooks and styles of lacers, inexpensive to manufacture, and durable under conditions of repeated and continued use.

In carrying out the purposes of the invention,

it is proposed to provide a belt-hook magazine having separate transverse slots for individual hook members, and having within the lower part of the slotted portion a straight clamping elethe center line of the assembly, whereby to clamp the hooks collectively and in dividually against a straight pin member inserted prior to, and removed after, the operation of the inserting and clinching jaws of the belt-lacing .machine with which the device may be used.

' The nature of the invention, however, will best be understood when described in the accompanying drawings, in which:

Fig, 1 is a partially exploded front elevation of the magazine with portions shown in section; and Fig. 2 is a similar plan thereof.

Fig. 3 and 4 are respective end elevations of the magazine.

Fig. 5 is a front elevation of the magazine loaded with belt hooks.

Fig. 6 is a transverse section taken on the line 66, Fig. 5, and Fig. 7 is a similar section, but with cam adjusted to locking position.

Referring now to the drawings, It designates a block of rectangular cross-section and of length somewhat greater than the width of the widest belting with which the tended to be connection with block toward the bottom or side remote from the grooves H is a cylindrical opening l2; and between said opening and the grooves is a rectangular, longitudinal slot I3 which intersects radially the cylindrical opening it? and extends also through a portion of the respective bottoms of grooves II.

'The interior boundary surface of said slot on the side remote from opening I2, is near to, but within, the face or top of the block into which the grooves are cut, and is of semicircular crosssection.

A cam member l5 of axial length somewhat greater than that of the block I0, is provided with cylindrical extremities l6 and I! turned to fit the bore of the opening l2, and with an intermediate portion !8 of a section cylindrical, or otherwise curved, about an axis eccentric with that of the extremities It and H, so that, as the member I5 is rotated about its longitudinal axis which coincides with that of the opening :2, the portion It will act as a cam.

An extended bar 20 of rectangular cross section, and having a thickness to provide a running fit in the longitudinal slot I3 and a length slightly less than that of the cam portion l8 of the member [5, formed preferably of steel, is adapted to rest with one face upon the eccentric surfacevofesaidocam portion-l8, whereby, with rotationnofrthe member l about its axis, said bar will be displaced radially through a limited distance in the slot semicircular interior surface of 'said slot.

An extended pin 2|, formed-preferably ofwsteelv rod having a cylindrical section of radius equal to, or slightly less than, that of the curvature of the interior surface of the longitudinal .slot i3, is provided with one pointed extremity 22' to facilitate its insertion into the slot l3,.: and an extremity 23 formed into a ring or hook or the like,-.wherebysaidupin may be readily manipulated. Airadiallyextending bar 2%, suitably fixed to;the-extremity I-Sof the member 45, serves as a. crank and facilitates manual rotation of the latter in operation;

As indicated in the drawings, Figs. 5 to '7, the device is shown with a groupof belt-hooks 25 insertedgin the: grooves H Y and having positioned betweenwtheir. inwardlydirected and sharpened extremities a section! of belting 25, towhich they are tozbec appliedt In- Figs. 6' and '7 said belthooksandbelting ,areindicated as positioned betweenaj'aws 1:2 1 which form. operative elements in a vise or conventional belt.-hook-applying machine; and-are adapted-to: be forcibly moved towardvone another :through a; limited distance.

In operatiomireferencerbeing had more particularlyto, Figs; 5i-to 'l,'themember I5 is rotated until the bar 20 is lying in its lowest position-i. e. most remote from the grooved surface of the block ID. A group of belt hooks'lfirsuited' to the width ofthe-belting- 261s,- then placed in the grooves H -.to project through the opening therein sufiiciently fa]: that ,theirrloopsapproach the upper surface of the bar 20." The pin 2! is then'inserted from: the end of the block Ill, passing through and being.- encincled. by; theloop portion of each of the-. belt-hooks; The: member I5 is then by means of the-bar rotated. about its axis, whereupon the portion l8; by virtue of its eccentric or oblique actions, will act as acarn, Fig- '1', and cause the bar Zll'to beforcedi-into. engagement with the bottom portions of. thebelt-hook loops, which; in turn engagethesurface of the pin 2i, forcing it into'contact 'with the curved interior surface of the slotl'3toprovide'a rigid anvil against which the belt-hooks willibe-solidly clamped with a unif ormly exerted straight-line action, symmetrically distributed, and devoid of oblique forces on the hooks and therefore free offi abrasive or rubbing action;

With'the-hooks clamped'jirr place in the block In; and the belting placed between their pointed ends as showrrin Fig. '7' and: the whole positioned between the'jaws 2'1,- theplatter are tobe forcibly brought together by means not shown in the drawings, and'formirrgno part of the present invention: Thepoints: ofthe hooks will thereby be forcedinto and through the material of the belting, and clinched therein; without possibility of displacement of anyof thehooks due-to the application of the relatively great pressures which are applied. The jaws-21 are then released, the member" I 5 rotated; to remove the clamping action of the bar 20, and the pin 2| withdrawn, after which the end ofthe belt 26 may be removed from the apparatus-with the desired group of hook elements uniformly. and securely applied, and adapted tabeinterleaved witha similar group I3 within the block 10, tends. ing to approach, or recedefrom the curved or.

(not shown) on the opposite extremity of the belt, and secured thereto in hinged relationship as is well, understood,fort-example,v by means of a suitable rod. or pin member duct. shown) I claim:
